Diffusion is the movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. A good example of diffusion is food colouring.

PCT: Proximal Convoluted Tubule
Proximal tubule connects the Bowmen’s capsule and the loop of Henle. Its inner epithelium is converted to a brush border in order to increase the efficiency of reabsorption. This tubule is basically responsible for reabsorbing all the nutrient back into the systemic blood from the filtrate. In addition, it also reabsorbs two-third of NaCl and water filtered into Bowman's capsule. Active transport of Na+ from the filtrate and into surrounding capillaries drives the reabsorption process.
DCT: Distal Convoluted Tubule
Distal convoluted tubule is located in between the loop of Henley and collecting duct. It does not have brush border in its lumen. Distal tubule helps to regulate pH of blood by regulating H+ ion concentration. Also, the regulation of calcium by hormones is taken place at distal convoluted tubule.
What is the difference between Proximal and Distal Tubule?
• Diameter of proximal tubule is larger than that of distal tubule.
• Epithelium of proximal tubule contains a brush boarder, whereas that of the distal tubule contains few short microvilli.
• Proximal tubule has an irregular or star shaped lumen. In contrast, distal tubule has perfectly round lumen.
• Proximal tubule connects the Bowman’s capsule and nephron loop (loop of Henle), whereas distal tubule connects nephron loop and collecting duct.
• Distal tubule helps to regulate pH and ions like potassium, sodium, calcium content in the blood, whereas proximal tubule regulates salt, water, organic solutes (glucose and amino acids), potassium, urea, phosphate and citrate contents.

A primary pulmonary lobule is defined as the lung unit distal to the respiratory bronchioles. It is significantly smaller than an acinus, and is composed of alveolar ducts, alveolar sacs and alveoli.

Decomposition can be aerobic or anaerobic. Two broad categories of microorganisms consume and decompose organic matter: those that need air (aerobic) and those that don't (anaerobic).
Dr Pathikrt Banerjee 7 years, 4 months ago
Can be aerobic or anaerobic. Increases in absence of oxygen.

Partial regulators change their body temperature to certain level of ambient temperature but if the temperature goes on increasing they can maintain a steady temperature.
ex-shrew (Sorex araneus), ground squirrel (Spermophilus tridecemlineatus).No because of small size they are partial regulators.

Shrew is an example of partial regulator. Others are regulators.

A pathogen is defined as anything that is able to cause a disease within a host. As such, a pathogen can be one of many types of microorganisms or particles such as bacteria, fungi, viruses, prions and parasites.
As such, we can say that all parasites causing a disease in human are pathogens, but it is incorrect to say that all pathogens are parasites, as they can be other types of microorganisms, viruses or prions. Following this definition, it is also incorrect to say that all parasites are pathogens as some are able to live as free-living organisms.
